ROCKlNG SEPARATOR AND STOP FOR LAClNG-HOOK-SETIING MACHINES.

SPECIFICATION forming part of Letters Patent No. 678,028, dated July o, 1901-.

f Application inea March 9,1901.

To CLZZ whom t may concern:

Be it known that I, JOHN PIERCE, a citizen. of the United States, residing at Milton, in the county of Norfolk audState of Massachu- A setts, have invented new and useful Improvements in Rocking Separators and Stops for Lacing-HoOk-Setting Machines, of`which the following is a specification.

This invention relates to that class of ma- Io chines in which articles such as lacing-hooks, buttons, rivets, and the likeY are fed from a hopper to a raceway and are taken from the raceway one by one after being set or attached to a piece of material.

I have illustrated and described my invenvention as adapted to a machine for setting lacing-hooks, and particularly as adapted to a machine for setting lacing-hooksI for which I have obtained Letters Patent of the United 2o States, dated September 1l, 1900,'No. 657,673. In machines of this class it is essential that the lacing-'hooks shall, first, not leave the raceway until after they have'been set in the upper of the boot or shoe; second, that the lowermost lacing-hook shall be correctly eentered and held in positionkabove the anvil upon which it is to be set, and, third, that after said lacing-hook is set in the shoe-upper lthe end ofthe raceway shall be free for the 3o removal of said lacing-hook therefrom as soon as the lacing-hook which has been set clears the anvil upon the upward movement of the raceway, and, further, that the next lacinghook on the raceway shall .descend to the 3 5 proper position upon the' raceway above the anvil while the other lacing-hooks in said race- Way are held back. It is very essential in machines of this class that the lacing-hooks shall not be manipulated or handled more than is 4o absolutely necessary from the time they leave the hopper until they are setin the shoe-upper. It is also essential in a machine of this class that as much time as possible should heallowed for the operator to remove the' lacinghook which has -been set in the upper of` the shoe from the raceway, and in the machine' of this invention `the devicefis so constructed and operated that the lacing-hook which has" been previously set inthefshoe-upper is free vbringing said stop and separator alternately 5o to be removed as soonas said lacing-hook` Serial lilo. 50,423. (No model.)

clears the top of the said anvil, and the parts are left in such a position that vthe operator may remove the said hook from the raceway at any time during the upward movement of the raoeway and plunger from the time the lacing-hook leaves the anvil until just before the plunger and raceway arrive at their up permost position. It is further essential in a machine ot this class that the lowermost hook upon the raceway should have sufficient time to pass into position before setting in the shoe-upper over the center of the anvil, and in the machine of this invention this is pro-V 'vided for, said lowermost lacing-hook having all the time to feed which is consumed by the raceway and plungerin their downward movement from their uppermost position until just before the'lacing-hook is set in the' upper of the shoe. p

The object of this invention is to provide a 7o combined separator and stop, positively operated, which shall fulfil the requirements hereinbefore recited. f

The invention consists in a separator and stop fast'to a rocker-shaft, said rocker-shaft having a bearing in a reciprocating plunger, said plunger having a raceway fast thereto, and mechanism for imparting an intermittent rocking motion to'said rocker-shaft,

into and out of line with the lacing-hooks on said raceway, stopping 'the last lacing-hook in line with ythe anvil, and separating the re'- mainder of the hooks on the raceway from said last hook.

8s The invention further consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure l is a right-hand side elevation of a portion of'a lac-A .ing-hook'machine, similar to that shown and ydescribed in my United States Letters Patent No. 657,673, with my improved rockingseparator and stop attached thereto. Fig. 2 is a 95 vertical sectional elevation taken on line 2 2, Fig. 1, looking toward the left in said figure,

the plunger, separator, and stop being shown in elevation. Fig. 3 is a rear elevation ofv a portion ofthe plunger, raceway, separator, Ioo

and stop, with a number of lacing-hooks on said raceway, the same being shown fullsize and starting to descend. Fig. 4 is a view similar to Fig. 3, with the parts shown in the relative positions assumed when the plunger is in its lowermost position and the lacinghook having been set in the material is being removed by the operator from the raceway. Fig. 5 is an enlarged right-hand side elevation of the parts shown in Fig. 3. Fig. 6 is a side elevation of the parts shown in Fig. 4. Fig. 7 is a perspective View of my improved separator and stop.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 is the base-plate of a machine for setting lacing-hooks similar in construction to that shown in my Letters Patent No. 657,673. 12 is the frame of the machine fast to said base-plate.

The lacing-hooks are placed in a hopper 30, from the bottom of which they are taken by an intermittently-rotated pickerplate 31, which is fast to a shaft 32, having a bearing 33 in the hopper 30.

The method of conveying lacinghooks by a picker-plate such as that shown from a hopper to a raceway is old and well known to those skilled in the art.

The pickenplate 3l has six fingers or arms 43. The lacing -hooks are taken by these arms from the bottom of the hopper, and as the picker-plate rotates in the direction of the arrow, Fig. 1, the lacing-hooks are picked up by said arms and carried from the bottom of the hopper, as shown, sliding around the curved edge of each arin of the picker-plate until each arm in its turn arrives at the position of the arm 43', with the straight edge 45 of said arm in line with the opening of the raceway 44, whereupon the lacing-hooks will slide down the straight edge 45 of the arn143 on the raceway 44.

The hopper 30 is cut off on its upper side at an angle of thirty degrees, so that as the lacing-hooks slide off the arm 43 they will not be interfered with by said hopper, but will be perfectly free to slide off of the arm 43 and onto the raceway 44, as hereinbefore described. It will thus be seen that as the picker-plate 3l rotates in the direction of the arrow, Fig. 1, the different blades thereof will emerge from the hopper at the right-hand side thereof,and the lacing-hooks thereon will slide olf of the back edge 43 of each arm before said arm enters the hopper again, thus leaving the way free for said lacing-hooks to slide off the picker-plate and onto the reciprocatory raceway without danger of being stopped by the walls ofthe hopper.

In order to prevent dirt from falling into the hopper, I provide a cover 79, hinged at SG to the hopper 30. The raceway 44 is made of two pieces of fiat steel 46 47, the part 47 being fastened to the part 46 by blocks 48. The plate 46 is fastened rigidly to the vertically-reciprocating plunger 49 by a screw 50,

iFigs. 4 and 6.

stud 5l, and screw 52. The stud passes through the plunger 49 and receives a sliding block 53, said sliding block entering a slot 54 in a lever 55. Said lever 55 is pivoted to a stud 56, fast to the frame 12, and is rocked upon said stud by a cam fast to the main shaft of the machine. The plunger 49 slides in bearings 59 59 in the frame l2, motion being imparted thereto by the lever 55. The raceway 44 passes downwardly outside the bearings 59 59 from the hopper 30 to the lower end of the lunger 49 where it curves under said plunger 49, ending in a short horizontal .portion GO.

My improved separator and stop consists of two disks or plates 13 and 14, respectively. Said plates are fastened to a rocker-shaft 15,

varranged to rock in a bearing 16, formed in The rockeri the lowerend of the plunger 49. shaft 15 is shouldered at each end to receive said plates, and each of said plates is attached to said rocker-shaft by a screw 17. The stop 14 and separator 13 are located upon opposite sides of a vertical plane passing through the center of the anvil 64, extending lengthwise of the plunger 49 and across the raceway 44, the stop 14 being located upon the opposite side of said plane from that by which the raceway 44 approaches the plunger. The stop 14 has a depression 1S in the periphery thereof, Which allows the head of the lowermost lacing-hook 25 to pass by said stop after said lacing-hook has been set and the plunger is raised sufficiently to clear the shank of the lacing-hook from the anvil, the parts being in the relative position shown in The stop 14 has a projection 19 upon the periphery thereof, which is moved across the path of the lacing-hook upon the raceway 44 when the said raceway and the plunger to which it is attached are raised to the position shown in Figs. 3 and 5. The separator-plate 13 has a depression 2O in the periphery thereof and a projection 21 upon said periphery, the depression 2O allowing the lowierinost hook of the column of hooks upon the raceway to pass along the raceway to a point thereon directly over the anvil, where said lowermost hook will come to a rest against the stop 14. The said separator-plate 13 has a thin V-shaped edge or periphery, so that it can be readily passed between two of the lacinghooks upon the raceway and separate the lowermost hook from the hook next to it.

It will be understood that the separatorplate 13 and stop-plate 14 are fastened. to the rocker-shaft 15 in such relation to each other and to the raceway 44 that when the depression 18 in the periphery of the stop-plate 14 is in position so that the lowermost hook may be removed from the raceway 44 the projection 21 upon the separator-plate 13 stands across the raceway 44 and holds back the hooks on said raceway, and when the projection 19 upon the stop-plate 14 stands across the raceway 44 and prevents the lowermost hook from being removed therefrom or from IIO accidentally sliding E of said raceway the depression upon the separator-plate 13 will be at that time in such a position with relation to the raceway 44 thatthe lowermost hook of the column of hooks upon said raceway can pass down said raceway and between the separator and stop-plates directly over the anvil, as shown in Fig. 2. This result is attained by fastening the separator-plate and stop-plate to the rocker-shaft 15, so that the depression 1S in the stop 14 comes in line with the projection 21 -upon the separatorplate 13 and the projection 19 on the stop 14 in line with the depression 20 on the separator-plate 13. It will therefore be seen and understood that when the projection upon one of the plates stands across the raceway and prevents the lowermost hook from traveling along said raceway the depression upon the other plate stands in line with said racewayand allows said lowermost hook to travel or be moved along the raceway. The separator and stop-plates are rocked from the position shown in Fig. 5 to that shown in Fig. 6, as follows: The stop-plate 14 has a finger 22 thereon,wh'ich abuts against a s top 23, fast to the frame of the machine, when the plunger 49 and raceway 44 are nearly arrived at their lowermost positions,t`ipping the separator and stop from the position shown in Fig. 5 to that shown in Fig. 6. When the plunger 49 and raceway 44 ascend, together with the separator and stop, a pin 27, fast to the stop-plate 14, strikes against the frame 12 of the machine and rocks the separator and stop 13 14 and the rocker-shaft 15 from the position shownin Fig. 6 to that shown in Fig. 5.

The operation of my improved rocking separator and stop in conjunction with the vertically-reciprocating plunger and rac'ewayis as follows: The lacing-hooks are delivered to the raceway 44 from the picker-plate 31 and slide down said raceway to the position shown in Fig. 3. The lowermost hook 25 restingv upon. the short horizontal portion of the raceway 44, with the left side of the head of said hook touching the right side of the projection 19 on the stop-plate 14, the Weight of the hook 26 and the column of hooks on the raceway pushes the hook 25 into the position shown in Figs. 2 and 3 andbrings said hook into a vertical position directly above the center of the anvil 64. The plunger 49 is shown raised in Figs. 2 and 3 and just beginning to' descend. The operator next places the upper-of the shoe in the proper position over the anvil 64, Fig. 2, andthe plunger descends.

As the plunger descends the rocker-shaftl,

with the stop and separator plates fast there` to, remains stationary with relation to the plunger and raceway until just before the shank of the lacing-hook 25 abuts against the leather of the shoe-upper, when the flnger22 strikes the stop 23 and tips the separator and stop plates 13 and 14, respectively, togetherwith the rocker-shaft 15, from the position shown in Fig. 5 to that shown in Fig.' 6. During the last part of the downward motion of the plunger 49 the shank of the lacing-hook.

that when the plunger and raceway, togetherr with the separator, stop, and rocker-shaft, start to ascend the lowermost lacing-hook can be removed from the raceway at any time after said lacing-hook has cleared the topV of the anvil 64 and until the pin 27 strikes the frame 12 of the machine, when upon the last part of the upward motion of the plunger the position of the separator and stop plates will be reversed and the depression 2O in the separator-plate will come in line with the lacinghooks upon the raceway, allowing the lowermost hook in the column of hooks to pass down said raceway and against the projection 19, which by that time will have been rocked into position in line with the lacing-hooks upon said raceway. It will also be seen that the lowerrnost hook of the'column of hooks upon the raceway has all of the time occupied IOO lacing-hook is held between the two projectio-ns 19 and 21 as the shank ofthe lacinghook first enters the upper and while it ispassing through it, and thus holds said lacing-hook firmly in position 'during the setting -operation.

It will be seen that the shape and style of the separator and stop plates may be varied without departing from the spirit of my invention. For instance,the separator-plate and stop-plate may in each case be formed as a finger fastened at different angles to the rocker-shaft 15, so that as said rocker-shaft is rocked said fingers will be moved alternately into'and out of the path of the lacing-hooks the'mechanism or means by which a rocking movement is imparted to the rocker-shaft 15 andto the separator and stop 13 and 1 4, respectively,'may be varied without departing from the spirit of my invention, and ,further, that the shape, size,and style of the plunger IIO . US upon the raceway. It will also be seen that and its manner ot' attachment to the raceway is immaterial so longas a reciprocating motion'is imparted to the raceway.

Having thus described my invention, what I claim, and desire by Letters Patent toy secure, is
